“…We could also show differences in the most important factors between the groups (hypothesis (3)). The formation of characteristic assemblages in these two taxonomic groups for the study sites in the research area has been shown in former studies, e.g., Szyszko-Podgórska [33]; Schwerk et al [70]. The sensitive reaction of carabid beetles to soil pH has also been previously reported, e.g., Koivula [25]; Zumstein et al [71]; Nietupski et al [72].…”

A drastic decline in insect fauna on a large scale has been reported. We assume that this is a multifactorial problem involving biotope types and plant diversity, soil characteristics and human activity (management of areas). The aim of our study was to analyze diversity patterns of carabid beetles and butterflies as predatory and phytophagous arthropod groups in response to soil characteristics and plant diversity in different types of ecosystems and ecotones with diverse management situated in a heterogeneous landscape composed of different forests, agricultural and post-agricultural areas of different stages of succession and watercourses and mires in north-western Poland. Three different forests, three fallows, two meadows and two ecotones, differing with respect to the involved ecosystems, were included in the study. Our results showed that the study site types differed with respect to soil characteristics and plant diversity, but ecotones were not characterized by explicitly higher diversity in these parameters. For both carabid beetles and butterflies, characteristic assemblages for individual study sites could be demonstrated. We could also show differences in the most important factors between these two taxonomic groups. We assume that management type is important regarding ecosystem characteristics and biodiversity. Large-scale management strategies are necessary in order to maintain or create landscapes with high natural qualities.

“…In the second year, LAI remained a signi cant factor, but some other factors were also signi cant, namely high soil temperature (in areas between tree crowns on the ground) and soil carbon content (for carabids living in the least disturbed stands and under tree crowns). Higher C content in the organic soil layer is conducive to forest assemblages of carabids (Schwerk et al 2020), because it is associated with greater species diversity of litter and soil micro-and macrofauna, which results in better trophic conditions for forest species of ground beetles associated with forest litter.…”

Abandonment of salvage logging in windthrown stands is key to protection of late-succession carabid assemblages

The usual practice in forest stands following a windthrow event is to perform salvage logging of all broken trees with their crowns before seedlings are planted. Does leaving broken tree crowns on the ground afford shelter for forest species? Epigeic carabids (Coleoptera) were the test taxon. The following hypotheses were put forward: (1) the more severe the disturbance, the higher the abundance and species richness, and the lower the proportion of late successional fauna in carabid assemblages, (2) crowns of pine trees lying on the ground support a higher proportion of late-successional carabid species, which effect should be more pronounced in more severely disturbed stands, but will decrease as needles fall off over the next 3 years. In order to verify the first hypothesis, 3 variants of stand disturbance (severely, moderately and least disturbed stands) were distinguished. The second hypothesis was verified by distinguishing additional variants at locations under and between tree crowns in the severely and moderately disturbed stands. Hypothesis 1 was proved correct and hypothesis 2 was proved partially correct. Simultaneously, it was demonstrated that the importance of the leaf area index for carabids decreased over the 3 years, while the significance of environmental indices, such as soil respiration rate and soil humidity, increased. This study indicates that there is a rationale for leaving in place at least some crowns lying on the ground in windthrown forest stands to provide shelter for forest species.

The usual practice following a windthrow event is salvage logging of all damaged trees. This study was carried out in a pine stand affected by storms with varying disturbance severities in which no salvage logging was performed. Epigeic carabids (Coleoptera) were the test taxon. How does windthrow severity and disturbance legacies affect the abundance, richness and life traits of carabid assemblages? Two hypotheses were formulated: (1) the more severe the disturbance, the higher the abundance and species richness, and the lower the proportion of late-successional fauna in carabid assemblages, and (2) pine tree crowns lying on the ground support a higher proportion of late-successional carabid species, the effect of which should be more pronounced in more severely disturbed stands but will decrease as needles fall off over the next 3 years. To test the first hypothesis, 3 degrees of stand disturbance were distinguished. Both hypotheses were partially supported. Simultaneously, it was demonstrated that the importance of the leaf area index for carabids decreased over the 3 years, while the significance of the soil respiration rate and soil humidity increased. During the 3 years, the percentage of carabid forest species living under the fallen tree crowns remained at the same level. The findings indicate that there is a rationale for leaving fallen trees in place together with their crowns, while in tree stands where salvage logging is performed, whole crowns should be left cut-off from trunks to provide shelter for forest species.
